Hi there! It sounds like you're having trouble with the worksheet tabs not showing up at the bottom of your Vista laptop display in Excel 2003. Don't worry, there's an easy fix for this.

1. Right-click on any of the existing tabs at the bottom of your Excel window.
2. Click on "Unhide" from the drop-down menu.
3. In the "Unhide" dialog box, select the worksheet that you want to unhide.
4. Click "OK" to close the dialog box.

If this doesn't work, try the following:

1. Click on the "Tools" menu at the top of the Excel window.
2. Click on "Options" from the drop-down menu.
3. Click on the "View" tab.
4. Under the "Window options" section, make sure that the "Sheet tabs" checkbox is checked.
5. Click "OK" to close the dialog box.

If you still can't see the worksheet tabs, it's possible that they are hidden behind the Windows taskbar. To fix this, you can either move the taskbar to a different location on your screen or resize it.
